在高中数学教学中,立体几何是学生学习的一个难点。而引入向量这一知识,则为立体几何中空间问题的解决,提供了非常实用和方便的解题工具。利用向量可以解决立体几何中的许多问题,如面面平行、线面垂直、空间角等问题。对于立体几何问题,如果用传统的纯几何的方法,往往比较费时、费力,学生由
In high school mathematics teaching, three-dimensional geometry is a difficult point for students to learn. The introduction of the vector of knowledge, the space for the three-dimensional geometry to solve the problem, provides a very practical and convenient solution to the problem. The use of vectors can solve many problems in solid geometry, such as face parallel, line face vertical, spatial angle and other issues. For the three-dimensional geometry, if the traditional pure geometric approach, often more time-consuming, laborious, students from
